I would definitely report to google because of the duplicate issue. This used to happen to GamesandCasino a lot, but since we put up a script that forbids frames we see a lot less of it.
I will start by contacting visitorserver.com ([email protected]) and try to find out what is going on. Something like that happen to me with an atv racing website that I run and the google report is a headache takes forever… Yahoo was a little easier for me :p
